Impacts

Damaged & destroyed buildings

There are two main sources for building damaged and destroyed buildings; AFAD official sources which are aggregated at the nationa-level; and buildings tagged as destroyed in OpenStreetMap, through the ongoing voluntary efforts, using available satellite and drone imagery. While tagging of destroyed buildings in OSM is ongoing, the completenessof the tagging will vary betweeen areas. This dataset will be updated frequently to incorporate the additional data. Progress of the tagging, can be found on the OSM website.

As of 11:23 UTC on 8/02/2023, 3529 buildings have been identified as destroyed, 3519 of which are in Türkiye.
